Yep, I reckon that's an improvement on the two - the colour is better than your first one, and the stars are tighter than your 'red' version. But gawd it's a fiddly process, so delicate to get a colour that feels right! I've spent way too long carefully getting images terribly wrong in the past
.
You should get a better result with longer exposures, 2 mins, 5 mins, whatever your skies, camera, alignment and tracking can handle (I'm not sure of 10mins from Mt Waverley at ISO1000 though without the skyglow washing out the picture? but you can always try!). Longer subs should get you more signal, particularly getting the reds above the noise threshold to play with as well.
If you're passing the Fish Inn on High Street Road, have one for me - I miss his tasty bluey and minimum chips on a Friday, used to live round the corner from there!
